"I fall between fatigue and narcolepsy.  Things like falling aslleep at traffic lights, work and at home.  The doctor thought it might be the side effect of sleep apnea, so I took the test and ended up very low (6x per hour).  I was put on Provigil which I soon fell asleep on, then on to Nuvigil, which wasn't strong enough.  Ritalin was next but it gave a big crash when it ebbed.  Now I am on dextroamphetamine and it is helping immensley.  No more falling asleep in the car or at work and at home (which was putting a strain on my marrage.)"
